鲁东地区旭口组与近浅海全新世沉积地层特征

Characteristics of Holocene Sedimentary Strata in Offshore and Xukou Formation in East Shandong

摘要:

山东省近浅海全新世沉积与旭口组的地层结构、纵横向变化、沉积环境是相同或相似的沉积环境中形成的相似岩石组合。旭口组的含义应扩大到浅海 ,全新世以来在浅海附近 ,海水动力作用形成的潮流砂体、潮滩、河口、砂坝、砂堤、浅滩砂等海积砂体 ,夹有少量砾石和淤泥层 ,时代定为全新世

Abstract:

Holocene sedimentary of offshore and shallow sea and Xukou formation in Shandong are similiar in strata structures, vertical and transverse variation, sedimentary environment which formed in the same or similiar sedimentary environment and have similiar rock combination. Meaning of Xukou formation should extend to shallow sea and the formation is composed of tidal current sandbodies, tidal beach, stream outlet, sand dam, etc. which is with little gravel sandbodies and mudy formed by sea hydraulic function n...
